Gold Process Mineralogy: Objectives, Techniques, and
INTRODUCTION Based on the gold recovery and mineral processing techniques required, gold ores are commonly classifi ed into two major categories: free-milling and refractory ores. Typically, free-milling ores are defi ned as those where over 90% of gold can be recovered by conventional cyanide leaching.

Recovery of gold from refractory gold ores: Effect of pyrite on the
The extraction of gold from refractory gold ores (RGOs) without side reactions is an extremely promising endeavor. However, most RGOs contain large amounts of sulfide, such as pyrite. Thus, investigation of the influence of sulfide on the gold leaching process is important to maximize the utilization of RGOs. In this work, the effects of pyrite on the …
